Description

本発明は、空気調和機のファン室構造、特に、ファン室の防振構造、及び、気密構造の技術分野に属する。   The present invention belongs to the technical field of a fan chamber structure of an air conditioner, in particular, a vibration isolation structure of a fan chamber and an airtight structure.

従来より、空気調和機のファン室にはファンモータユニットが設置されている。このファンモータの振動をファン室の枠体に伝えないために、特許文献１、特許文献２等に示されるように、ファンモータを載置した上部架台にはバネやゴム等の吸振体を有する防振装置（振動絶縁機構）が設けられている。
例えば、従来の空気調和機では、図５に示すように、ファン室ａではコイル空調室ｂからの空気調和された空気を、モータユニットｃに駆動される一対のファンユニットｄによって、給気室ｅに供給する。
前記のモータユニットｃに駆動されるファンユニットｄは、振動を発生することから騒音の原因になる。そのため、ファン室ａの振動を空調機全体の枠体から遮断しなければならないが、通常、ファン室ａの床にファン架台ｆ上に吸振部材ｇを介して設けられた防振架台ｈに載置されている。 Conventionally, a fan motor unit is installed in a fan chamber of an air conditioner. In order not to transmit the vibration of the fan motor to the frame of the fan chamber, as shown in Patent Document 1, Patent Document 2, etc., the upper frame on which the fan motor is mounted has a vibration absorber such as a spring or rubber. An anti-vibration device (vibration isolation mechanism) is provided.
For example, in a conventional air conditioner, as shown in FIG. 5, in a fan chamber a, air conditioned air from a coil air-conditioning chamber b is supplied by a pair of fan units d driven by a motor unit c. e.
Since the fan unit d driven by the motor unit c generates vibration, it causes noise. For this reason, the vibration of the fan chamber a must be isolated from the frame of the entire air conditioner. Normally, the fan chamber a is mounted on a vibration isolation frame h provided on the fan frame f on the floor of the fan chamber a via a vibration absorbing member g. Is placed.

この際にファン室ａのファン架台ｆと給気室ｅとが固定されているが、モータユニットｃ、ファンユニットｄ、防振架台ｈは振動しているので、ファンユニットｄと給気室ｅとの間は、ファン室aの室内の空気(Air.Ａ)がファンによって吸引されるため負圧になる。このことから、ファン室aと給気室ｅとの間に隙間があると、給気室ｅから空気(Air.Ａ)を吸い込んでしまい、コイル空調室ｂを通過せずにバイパスを形成して効率が低下するので、ファン室aと給気室ｅとを気密に維持するように、気密性があり柔軟性のあるキャンバスiで塞ぐようにしている。   At this time, the fan base f and the air supply chamber e of the fan chamber a are fixed. However, since the motor unit c, the fan unit d, and the anti-vibration base h vibrate, the fan unit d and the air supply chamber e. The air in the room of the fan chamber a (Air.A) is sucked by the fan, resulting in a negative pressure. Therefore, if there is a gap between the fan chamber a and the air supply chamber e, air (Air.A) is sucked from the air supply chamber e, and a bypass is formed without passing through the coil air-conditioning chamber b. Therefore, the fan chamber a and the air supply chamber e are sealed with an airtight and flexible canvas i so that the fan chamber a and the air supply chamber e are kept airtight.

ところで、図５に示す従来のファン室の構造は、ファン室aと給気室ｅとの間を振動を伝えずに気密にするために、キャンバスiを取り付けるには手間暇がかかるという問題があり、また、上述したように、モータユニットｃやファンユニットｄを備え付けるために、ファン架台ｆ上に吸振部材ｇを介して設けられた防振架台ｈに載置しなければならないため、このためのファン室aの天井までの高さがかなり必要となり、ファン室aが大型になってしまうという問題があった。
本発明は、上記の問題点に鑑みてなされたもので、ファン室と給気室のキャンバスを不用にし、振動の伝達を遮断して騒音を低減し、ファン室の高さをより低くすることが可能な空気調和機のファン室構造を提供することにある。 By the way, the structure of the conventional fan chamber shown in FIG. 5 has a problem that it takes time and labor to attach the canvas i in order to make the airtightness between the fan chamber a and the air supply chamber e without transmitting vibration. In addition, as described above, in order to provide the motor unit c and the fan unit d, the motor unit c and the fan unit d must be mounted on the vibration isolation frame h provided on the fan frame f via the vibration absorbing member g. There is a problem that the height of the fan chamber a to the ceiling is considerably required, and the fan chamber a becomes large.
The present invention has been made in view of the above-mentioned problems, and eliminates the need for the canvas of the fan chamber and the air supply chamber, cuts off the transmission of vibrations, reduces noise, and lowers the height of the fan chamber.

本発明の空気調和装置のファン室の構造の実施例を図面に沿って説明する。   An embodiment of the structure of the fan chamber of the air conditioner of the present invention will be described with reference to the drawings.

図１は空気調和装置Ａのファン室１と給気室の概略を示す実施例１の正面図であり図２はその側面図で、ファン室１では、熱交換器や加湿器等が配備されるコイル空調室７からの空気調和された空気を、ファン室１内の配備されるモータユニット３とそれによって駆動される一対のファンユニット４によって給気室８に供給している。
ファン室１のファン室枠体１１の上部の天井部分には防振部材５を介してファンモータ基盤１２が設けられ、このファンモータ基盤１２のほぼ中央部にはモータユニット３が吊り下げられるように固定され、このモータユニット３は両端に駆動軸３１が張りだした駆動モータ３２が設けられ、両端に駆動軸３１にはそれぞれプラグファン等のファンユニット４がファンモータ基盤１２に吊り下げられるように設けられている。 FIG. 1 is a front view of a first embodiment showing an outline of a fan chamber 1 and an air supply chamber of an air conditioner A. FIG. 2 is a side view thereof, and a heat exchanger, a humidifier, and the like are provided in the fan chamber 1. The air-conditioned air from the coil air-conditioning chamber 7 is supplied to the air supply chamber 8 by the motor unit 3 disposed in the fan chamber 1 and the pair of fan units 4 driven thereby.
A fan motor base 12 is provided on the ceiling of the upper part of the fan chamber frame 11 of the fan chamber 1 via a vibration isolating member 5, and the motor unit 3 is suspended from substantially the center of the fan motor base 12. The motor unit 3 is provided with drive motors 32 with drive shafts 31 extending at both ends, and fan units 4 such as plug fans are suspended from the fan motor base 12 at the drive shafts 31 at both ends. Is provided.

ファン室１のファンモータ基盤１２の上面の空気ダンパ室８１は給気室８の一部を形成するが、ファンモータ基盤１２のファンユニット４の天井に位置する部分には、給気室８の空気ダンパ室８１に連通する大きな給気開口１３が設けられ、ファンユニット４からの空気を空気ダンパ室８１及び給気ダクト８２に送風するように構成されている。本実施例１のファンユニット４はプラグファンのファンランナーを組み込んだもので、左右一対に配備されている。
ファンモータ基盤１２とファン室枠体１１のファンモータ基盤受け枠１１１の上面1111との間の適所には、複数の防振部材５を配置するが、防振部材５自体は図３に示すように公知の構成で、バネ５１やゴム５２等の吸振体を有する防振機構（振動絶縁機構）が設けられ、モータユニット３やファンユニット４で生じるファンモータ基盤１２の振動をファン室枠体１１に伝達しないような構成で、振動を効果的に遮断するようにしている。 The air damper chamber 81 on the upper surface of the fan motor base 12 of the fan chamber 1 forms a part of the air supply chamber 8, but the portion of the fan motor base 12 located on the ceiling of the fan unit 4 has the air supply chamber 8. A large air supply opening 13 communicating with the air damper chamber 81 is provided, and air from the fan unit 4 is blown to the air damper chamber 81 and the air supply duct 82. The fan unit 4 of the first embodiment incorporates a fan runner of a plug fan, and is arranged in a pair of left and right.
A plurality of anti-vibration members 5 are arranged at appropriate positions between the fan motor base 12 and the upper surface 1111 of the fan motor base receiving frame 111 of the fan chamber frame 11, and the anti-vibration members 5 themselves are as shown in FIG. 1 is provided with a vibration isolating mechanism (vibration insulating mechanism) having a vibration absorber such as a spring 51 and rubber 52, and the fan chamber frame 11 The vibration is effectively cut off with a configuration that does not transmit to the motor.

次に、本発明の特徴部分であるファンモータ基盤１２とファン室枠体１１(ファンモータ基盤受け枠111）との隙間を覆う気密部材６について説明する。
この気密部材６は、主に、バイパス防止板６１(リーク防止のパッキンシート)と保護パッキン６２と当て板６３とから構成される。
バイパス防止板６１はゴム板等の振動を吸収して伝達しない柔軟材質を用い、ファン室枠体１１(ファンモータ基盤受け枠111）とファンモータ基盤１２との外周の隙間を覆うように配置し、バイパス防止板６１の上端面６１１はファンモータ基盤１２の側面下部１２２に接着剤１２３で貼り付け、バイパス防止板６１の下端面６１２はファン室枠体１１に設けたファンモータ基盤受け枠１１１の側面上部1112に非接着状態で接触している。この際、ファンユニット４によりAir.Ａが吸い込まれ、ファン室１が負圧となるのでバイパス防止板もファン室内部に吸い寄せられ、枠体１１のファンモータ基盤受け枠１１１との接合面は非接着状態でも完全に気密となる。 Next, the airtight member 6 that covers the gap between the fan motor base 12 and the fan chamber frame 11 (fan motor base receiving frame 111), which is a characteristic part of the present invention, will be described.
The hermetic member 6 mainly includes a bypass prevention plate 61 (a leak prevention packing sheet), a protective packing 62, and a contact plate 63.
The bypass prevention plate 61 is made of a flexible material that does not absorb and transmit vibrations such as a rubber plate, and is disposed so as to cover the outer peripheral clearance between the fan chamber frame 11 (fan motor base receiving frame 111) and the fan motor base 12. The upper end surface 611 of the bypass prevention plate 61 is attached to the lower side surface 122 of the fan motor base 12 with an adhesive 123, and the lower end surface 612 of the bypass prevention plate 61 is attached to the fan motor base receiving frame 111 provided on the fan chamber frame 11. The side upper surface 1112 is in non-adhesive contact. At this time, Air.A is sucked in by the fan unit 4 and the fan chamber 1 becomes negative pressure, so that the bypass prevention plate is also sucked into the fan chamber, and the joint surface of the frame 11 with the fan motor base receiving frame 111 is not It is completely airtight even when bonded.

本実施例１において、ファンモータ基盤１２の側面下部１２２の垂直位置は、ファン室枠体１１のファンモータ基盤受け枠１１１の側面上部1112の垂直位置よりも内側で、図３に示されるように、側面下部１２２と側面上部1112とを覆うバイパス防止板６１の全体の形状はスカート状を呈している。
このバイパス防止板６１はゴムなどの柔軟材質であるので振動の伝達を遮断できるが、稼働の際にはファン室１が常に負圧になり、バイパス防止板６１がファン室１の内部側に吸い寄せられる力が働くので、バイパス防止板６１だけでは内側に湾曲するように変形するので、金属(亜鉛鋼板)等の硬質材料の当て板６３をバイパス防止板６１の中間面６１３の内側に設けてバイパス防止板６１の変形を防止する。また、当て板６３の斜面６３１の高さは、大きな振動があっても、先端がファンモータ基盤１２、例えば、基盤底面１２１に当たって騒音等を生じないように十分な間隔ｘを有するようにしてあり、枠体１１のファンモータ基盤受け枠１１１とバイパス防止板６１との接合面は非接着状態であることと相俟って、振動を遮断する構成としている。
この金属板等の硬質素材の当て板６３は、スカート形状に合うように、斜面６３１がバイパス防止板６１の中間面６１３に面接触するようにファンモータ基盤受け枠１１１の上面1111にボルト６３２や、後述する実施例２に示されるクリップ６３４の固着手段等で固定されている。
なお、ファン室１が稼働時に負圧になり、この負圧によりバイパス防止板６１がファンモータ基盤受け枠１１１の側面上部1112に密着するので、バイパス防止板６１に強度があり、ファン室１の負圧もそれほど大きくなく、バイパス防止板６１だけでも変形しないのであれば、前記当て板６３や保護用パッキンも不要である。 In the first embodiment, the vertical position of the lower side surface 122 of the fan motor base 12 is inside the vertical position of the upper side surface 1112 of the fan motor base receiving frame 111 of the fan chamber frame 11, as shown in FIG. The entire shape of the bypass prevention plate 61 that covers the lower side surface 122 and the upper side surface 1112 has a skirt shape.
Since the bypass prevention plate 61 is made of a flexible material such as rubber, vibration transmission can be cut off. However, during operation, the fan chamber 1 always has a negative pressure, and the bypass prevention plate 61 sucks toward the inside of the fan chamber 1. Therefore, the bypass prevention plate 61 alone is deformed so as to be curved inward, so that a contact plate 63 made of a hard material such as metal (zinc steel plate) is provided inside the intermediate surface 613 of the bypass prevention plate 61 to bypass. The deformation of the prevention plate 61 is prevented. Further, the height of the inclined surface 631 of the contact plate 63 is set to have a sufficient interval x so that the tip does not hit the fan motor base 12, for example, the base bottom surface 121, and no noise is generated even if there is a large vibration. The joint surface between the fan motor base receiving frame 111 of the frame 11 and the bypass prevention plate 61 is configured to block vibrations in combination with the non-adhered state.
The base plate 63 made of a hard material such as a metal plate has bolts 632 and the like on the upper surface 1111 of the fan motor base receiving frame 111 so that the slope 631 comes into surface contact with the intermediate surface 613 of the bypass prevention plate 61 so as to match the skirt shape. The clip 634 is fixed by a fixing means or the like shown in Example 2 described later.
The fan chamber 1 becomes negative during operation, and the negative pressure causes the bypass prevention plate 61 to be in close contact with the upper side surface 1112 of the fan motor base receiving frame 111. If the negative pressure is not so great and the bypass prevention plate 61 alone is not deformed, the abutting plate 63 and the protective packing are not necessary.

また、バイパス防止板６１の内側と当て板６３の間には、バイパス防止板６１よりはやや硬質ではあるが変形可能な柔軟材料の保護用パッキン６２を当て板６３の斜面６３１に接着剤６２１で固定して介在させている。
この保護用パッキン６２は、当て板６３の斜面６３１の高さを低くして、先端がファンモータ基盤１２の基盤底面１２１に当たらないように間隔ｘを有しているが、この間隔ｘでの大きな負圧によるバイパス防止板６１の変形を防止するように補強したもので、また、バイパス防止板６１と当て板６３との摩耗も防止している。保護パッキン６２自体の高さは、図３に示すように、通常では基盤底面１２１に当たらないように、それよりも保護パッキン６２の上端を若干低くしてある。
なお、保護用パッキン６２は、バイパス防止板６１の変形がほとんど無く、また、摩耗が激しくなければ省略してもよく、この場合でも、当然にバイパス防止板６１とファンモータ基盤１２との接合面は接着固定され、バイパス防止板６１とファン室枠体１１のファンモータ基盤受け枠１１１の側面上部との接合面は接圧するだけで非接着状態とし、振動は遮断する構成とする必要がある。
給気室８の空気ダンパ室８１の天井部１１２はファン室枠体１１でもあるが、空気ダンパ室８１の底面は振動するファンモータ基盤１２であっても、その間には防振部材５が介在しているので、振動が天井部に伝達することはなく、天井部１１２は設置床に対して固定している。したがって、給気室８の給気ダクト８２への振動も遮断される。
なお、ファン室１が稼働時に負圧になり、この負圧によりバイパス防止板６１がファンモータ基盤受け枠１１１の側面上部1112に密着するので、バイパス防止板６１に強度があり、ファン室１の負圧もそれほど大きくない場合で、バイパス防止板６１だけでも変形しないのであれば、前記当て板６３や保護用パッキン６２も不要である。 Further, between the inner side of the bypass prevention plate 61 and the contact plate 63, a protective packing 62 made of a flexible material that is slightly harder than the bypass prevention plate 61 but is deformable is attached to the inclined surface 631 of the contact plate 63 with an adhesive 621. It is fixed and interposed.
The protective packing 62 has an interval x so that the height of the inclined surface 631 of the contact plate 63 is lowered and the tip does not contact the base bottom surface 121 of the fan motor base 12. It is reinforced so as to prevent the bypass prevention plate 61 from being deformed by a large negative pressure, and wear of the bypass prevention plate 61 and the contact plate 63 is also prevented. As shown in FIG. 3, the height of the protective packing 62 itself is slightly lower than the upper end of the protective packing 62 so as not to hit the base bottom surface 121.
The protective packing 62 may be omitted if there is almost no deformation of the bypass prevention plate 61 and the wear is not severe. Even in this case, naturally, the joint surface between the bypass prevention plate 61 and the fan motor base 12 is used. Are bonded and fixed, and the joint surface between the bypass prevention plate 61 and the upper side surface of the fan motor base receiving frame 111 of the fan chamber frame 11 is brought into a non-adhered state only by contact pressure, and the vibration must be cut off.
Although the ceiling 112 of the air damper chamber 81 of the air supply chamber 8 is also the fan chamber frame 11, even if the bottom surface of the air damper chamber 81 is the vibrating fan motor base 12, the vibration isolating member 5 is interposed therebetween. Therefore, vibration is not transmitted to the ceiling portion, and the ceiling portion 112 is fixed to the installation floor. Therefore, vibration to the air supply duct 82 of the air supply chamber 8 is also blocked.
The fan chamber 1 becomes negative during operation, and the negative pressure causes the bypass prevention plate 61 to be in close contact with the upper side surface 1112 of the fan motor base receiving frame 111. If the negative pressure is not so great and the bypass prevention plate 61 alone is not deformed, the contact plate 63 and the protective packing 62 are not necessary.

本発明の実施例１は、以上ような構成であるので、その作用・効果は、ファン室枠体１１の上部のファンモータ基盤１２に、駆動モータ３２とファンユニット４を吊り下げるように取り付けたので、従来のファン架台が不用になり、ファン室の高さをより低くすることが可能となり、本実施例では、約２０〜３０cmも高さを短縮できた。また、ファン室枠体１１とファンモータ基盤１２との外周隙間Ｂに気密部材６としてバイパス防止板６１を設けるようにしたので、従来の気密維持のキャンバスが不要となり、空調機の設置作業が簡略化できた。
また、バイパス防止板６１がゴムなどの柔軟材質であるので振動の伝達を遮断でき、金属等の硬質材料の当て板６３をバイパス防止板の内側に設けたので、ファン室１の負圧によるバイパス防止板６１の変形を防止できる。
また、バイパス防止板６１のファンモータ基盤１２と接合面は接着し、枠体１１のファンモータ基盤受け枠１１１との接合面は非接着状態とし、また、当て板６３の垂直面６３３の高さを、大きな振動があっても、先端がファンモータ基盤１２の基盤底面１２１等に当たって騒音等を生じないように十分な間隔ｘを有するようにしてあり、前記ファンモータ基盤受け枠１１１との接合面は非接着状態であることと相俟って、振動を遮断する構成としている。
さらなる利点として、設置が極めて容易となり、加えて、稼働時にはファン室１が負圧となるのでバイパス防止板６１がファン室１内部に吸い寄せられ、枠体１１との接合面は非接着状態でも完全に気密とすることができる。 Since the first embodiment of the present invention is configured as described above, the operation and effect thereof are attached to the fan motor base 12 at the upper part of the fan chamber frame 11 so that the drive motor 32 and the fan unit 4 are suspended. Therefore, the conventional fan mount becomes unnecessary, and the height of the fan chamber can be further reduced. In this embodiment, the height can be shortened by about 20 to 30 cm. In addition, since the bypass prevention plate 61 is provided as the airtight member 6 in the outer peripheral gap B between the fan chamber frame 11 and the fan motor base 12, a conventional airtight maintenance canvas is not required, and the installation work of the air conditioner is simplified. I was able to.
Further, since the bypass prevention plate 61 is made of a flexible material such as rubber, the transmission of vibration can be cut off, and since the contact plate 63 made of a hard material such as metal is provided inside the bypass prevention plate, the bypass by the negative pressure of the fan chamber 1 is provided. The deformation of the prevention plate 61 can be prevented.
Further, the joint surface of the bypass prevention plate 61 and the fan motor base 12 is bonded, the joint surface of the frame 11 and the fan motor base receiving frame 111 is not bonded, and the height of the vertical surface 633 of the contact plate 63 is set. Even if there is a large vibration, a sufficient distance x is set so that the tip does not hit the base bottom surface 121 of the fan motor base 12 or the like to generate noise or the like, and the joint surface with the fan motor base receiving frame 111 In combination with the non-bonding state, the vibration is blocked.
As a further advantage, the installation becomes extremely easy. In addition, the fan chamber 1 becomes negative pressure during operation, so that the bypass prevention plate 61 is sucked into the fan chamber 1 and the joint surface with the frame body 11 is completely adhered even in a non-adhered state. Can be airtight.

更に、バイパス防止板６１と当て板６３との間には保護パッキン６２を介在させたので、この補強パッキン６２は、当て板６３と基盤底面１２１との間隔を大きくしても、この間隔ｘでの負圧によるバイパス防止板６１の変形を防止でき、バイパス防止板６１と当て板６３との摩耗も防止している。
実施例１では、バイパス防止板６１のファンモータ基盤１２と接合面の垂直位置が、枠体１１のファンモータ基盤受け枠１１１との接合面の垂直位置よりも内側に配置したので、常にバイパス防止板６１の下端は、バイパス防止板６１の自重によりファンモータ基盤受け枠１１１とバイパス防止板６１との接合面とが非接着状態でも密着し、ファン室１と給気室８とが完全に気密にした状態となる。 Further, since the protective packing 62 is interposed between the bypass prevention plate 61 and the backing plate 63, the reinforcing packing 62 can maintain the spacing x even if the spacing between the backing plate 63 and the base bottom surface 121 is increased. The deformation of the bypass prevention plate 61 due to the negative pressure can be prevented, and the wear of the bypass prevention plate 61 and the contact plate 63 is also prevented.
In the first embodiment, since the vertical position of the fan motor base 12 and the joint surface of the bypass prevention plate 61 is arranged on the inner side of the vertical position of the joint surface of the frame 11 with the fan motor base receiving frame 111, the bypass prevention is always performed. The lower end of the plate 61 is in close contact with the joint surface between the fan motor board receiving frame 111 and the bypass prevention plate 61 due to the weight of the bypass prevention plate 61 even when the fan motor 1 and the air supply chamber 8 are completely airtight. It will be in the state made.

本発明の別の実施例２は、図４に示すような気密部材６の構成が実施例１と異なるだけで、他は同じ構成であるので気密部材６以外の説明は省略する。
実施例２では、駆動モータ３２とファンユニット４の振動や余り大きくない場合のもので、バイパス防止板６１のファンモータ基盤１２と接合面の垂直位置と、枠体１１（ファンモータ基盤受け枠111）との接合面の垂直位置が同じにしている。 また、実施例１と同様に、当て板６３の垂直面６３３の高さを、大きな振動があっても、先端がファンモータ基盤１２の基盤底面１２１等に当たって騒音等を生じないように十分な間隔ｘを有するようにしてあり、枠体１１のファンモータ基盤受け枠１１１との接合面は非接着状態であることと相俟って、振動を遮断する構成としている。 Another embodiment 2 of the present invention is different from the first embodiment only in the configuration of the airtight member 6 as shown in FIG.
In the second embodiment, the vibration of the drive motor 32 and the fan unit 4 and the case where the vibration is not so great, the vertical position of the fan motor base 12 and the joint surface of the bypass prevention plate 61, the frame 11 (fan motor base receiving frame 111). ) And the vertical position of the joint surface are the same. Similarly to the first embodiment, the height of the vertical surface 633 of the abutting plate 63 is set at a sufficient interval so that even if there is a large vibration, the tip hits the base bottom surface 121 of the fan motor base 12 and no noise is generated. x, and the joint surface of the frame 11 with the fan motor base receiving frame 111 is configured to block vibrations in combination with the non-adhered state.

この実施例２では、ファンモータ基盤１２とバイパス防止板６１とが同一位置であるので、外周に平板のバイパス防止板６１を巻くだけでよく、取り付けが極めて簡単であり、当て板６３のバイパス防止板６１の中間面６１３の接面も、ファンモータ基盤受け枠１１１の上面1111に対して直角の垂直面６３３でよいので、制作も容易であり、実施例２ではファンモータ基盤受け枠１１１への当て板６３の取り付けもクリップ６３４で固着して、取り付け作業を簡単にしている。   In the second embodiment, since the fan motor base 12 and the bypass prevention plate 61 are at the same position, it is only necessary to wind a flat bypass prevention plate 61 on the outer periphery, and the attachment is extremely simple, and the bypass plate 63 is prevented from being bypassed. Since the contact surface of the intermediate surface 613 of the plate 61 may also be a vertical surface 633 perpendicular to the upper surface 1111 of the fan motor base receiving frame 111, production is easy. The attachment of the backing plate 63 is also secured by the clip 634, thereby simplifying the attachment work.

ただし、バイパス防止板６１の下端はファン室枠体１１の上面に屈曲して接するように十分長くして、多少の振動でも気密が保たれるようにしている。なお、バイパス防止板６１の上端面６１１はファンモータ基盤１２の側面下部１２２に接着剤１２３で貼り付け、バイパス防止板６１の下端面６１２はファン室枠体１１に設けたファンモータ基盤受け枠１１１の側面上部1112に非接着状態で接触するようにした点は実施例１と同じである。
また、作用・効果も実施例１とバイパス防止板６１の自重によるファンモータ基盤受け枠１１１での接合力がやや弱いだけで、他の作用・効果は同じであり、逆に、実施例１よりも製造や設定が容易である。
なお、本発明の特徴を損うものでなければ、上記の各実施例に限定されるものでないことは勿論である。 However, the lower end of the bypass prevention plate 61 is long enough to bend and contact the upper surface of the fan chamber frame 11 so that airtightness is maintained even with some vibration. The upper end surface 611 of the bypass prevention plate 61 is attached to the lower portion 122 of the side surface of the fan motor base 12 with an adhesive 123, and the lower end surface 612 of the bypass prevention plate 61 is the fan motor base receiving frame 111 provided on the fan chamber frame 11. This is the same as the first embodiment in that the side surface upper portion 1112 is brought into contact with the side surface upper portion 1112 in an unbonded state.
In addition, the operation and effect are the same as in Example 1 except that the joining force at the fan motor base receiving frame 111 due to the weight of the bypass prevention plate 61 is somewhat weak, and the other functions and effects are the same. Also easy to manufacture and set.
Of course, the present invention is not limited to the above-described embodiments as long as the features of the present invention are not impaired.
